Unilateral coronoid process atrophy associated with fatty degeneration of the masticatory muscles in a 76-year-old woman is reported. CT and plain radiogram findings are presented. The patient had no evidence of collagen disease which often causes osteolysis of the coronoid, process and condyle. Although the true cause of this deformity was unclear, a hypothesis of ischemic changes in the nutrient vessels was suggested as an etiologic factor. |
